Which is pretty much exactly the same as the previous model, the 8-Sided Compass Rose Jar. The difference is that this one is made from American letter paper (and it could be any size rectangle, really) and that instead of using that ?2/2 section to make the closure, this one repeats that section over and over, until it makes eight helical spirals up the sides.

Well, it more suggests eight helical spirals than actually creates them. Try it out, you’ll see. This is just the CP, but if you’ve successfully folded the 8-Sided model, you’ll be able to puzzle this one out pretty quickly.

I’ll hasten to add that this model squirms uneasily beneath the heel of the conceptual tyranny of 22½°-45°-90° angles.

Drawing this CP put me very much in mind of the Tholian Web episode of Star Trek.

i have a question for you
when you posted the instructions for your dollar to the donut…
when you create a crease do you fold it all the way across the bill or do you restrict it to its side? (the 45 degree angle part)
the same goes for the steps following it…

Today I haveve folded the 8-Sided Compass Rose Jar and the Star Vase.
No problems there.

I tried folding the Octuple Helix Compass Rose Jar too. I managed to
make all the creases on an A4 sheet of paper and I could partially
collapse it. But I could not collapse the spirals. The problem was I
could not align the two layers of the cylinder perfectly, it seems I
lacked precision even though I did my best to make all the creases in
place. Do you have any pointers to get it done?

Hm, it seems pretty accurate on letter paper – I’m guessing this is a scaling issue. With A4, you’ll want to make sure that the print dialog is scaling the page to fit. One way to test this is to see that the middle section is printed in even eighths. It could be that the outside eighths have been shorted a few millimeters. Not a lot, but enough to throw off the accuracy.

If that doesn’t work, let me know and I’ll scale the drawing and post an A4 version.

I’m at work and I’m supposed to not see things unrelated to work (damn call centres) but I couldn’t help noticing such a great design. I’m also a neophite with such complex models and though I’m not unfamiliar with paper folding, I hadn’t had the time to take origami seriously. Where are the instructions to fold this model? It’d be great if anyone could help me with this.
